Enable sign-in with web UI
Prerequisites
- An app setup according to the getting started walkthrough
Configure Auth Category
In terminal, navigate to your project, run amplify add auth (or if you've already added it, run amplify update auth), and choose the following options:
? Do you want to use the default authentication and security configuration? `Default configuration with Social Provider (Federation)`? How do you want users to be able to sign in? `Username`? Do you want to configure advanced settings? `No, I am done.`? What domain name prefix you want us to create for you? `(default)`? Enter your redirect signin URI: `myapp://callback/`? Do you want to add another redirect signin URI `No`? Enter your redirect signout URI: `myapp://signout/`? Do you want to add another redirect signout URI `No`? Select the social providers you want to configure for your user pool: `<hit enter>`Once finished, run amplify push to publish your changes.
Update AndroidManifest.xml
Add the following activity and queries tag to your app's AndroidManifest.xml file, replacing myapp with
your redirect URI prefix if necessary:
<application ...> ... <activity android:name="com.amplifyframework.auth.cognito.activities.HostedUIRedirectActivity" android:exported="true"> <intent-filter> <action android:name="android.intent.action.VIEW" /> <category android:name="android.intent.category.DEFAULT" /> <category android:name="android.intent.category.BROWSABLE" /> <data android:scheme="myapp" /> </intent-filter> </activity> ...</application>Launch Web UI Sign In
Sweet! You're now ready to launch sign in with web UI. For now, just add this method to the onCreate method of MainActivity:
Amplify.Auth.signInWithWebUI( this, result -> Log.i("AuthQuickStart", result.toString()), error -> Log.e("AuthQuickStart", error.toString()));Amplify.Auth.signInWithWebUI( this, { Log.i("AuthQuickStart", "Signin OK = $it") }, { Log.e("AuthQuickStart", "Signin failed", it) })try { val result = Amplify.Auth.signInWithWebUI(this) Log.i("AuthQuickStart", "Signin OK: $result")} catch (error: AuthException) { Log.e("AuthQuickStart", "Signin failed", error)}RxAmplify.Auth.signInWithWebUI(this) .subscribe( result -> Log.i("AuthQuickStart", result.toString()), error -> Log.e("AuthQuickStart", error.toString()) );
